An antifungal agent containing as the active ingredient a compound represented by general formula (I) or an acid-addition salt thereof, in particular, one having an absolute configuration of (R, R) at the asymmetric carbon atoms or an acid-addition salt thereof.
amino)-2-butanol derivatives I were prepared by ring-opening reaction of epoxides II with excess amine, and their antifungalactivities were evaluated as topical agents. Azolyl-cyclic amine derivatives with a methylene group showed extremely strong activity with a broad spectrum in vitro. In general, anti-Trichophyton mentagrophytes activities of most of the topical antifungalagents are substantially
